Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, and more specifically, to a communication method and apparatus. Background Technology
[0002] To address the issues of limited uplink time slot allocation in existing TDD systems, leading to significant uplink latency and restricted uplink coverage, the Rel-19 standard introduces subband full-duplex (SBFD) technology. In SBFD, a carrier can be divided into several subbands with different link directions. Base stations can simultaneously transmit signals on the downlink subband and receive signals on the uplink subband, thus reducing uplink latency and improving uplink coverage. However, SBFD introduces inter-link interference. For example, downlink signals transmitted by one base station on the downlink subband can interfere with uplink signals received by another base station on the uplink subband, a phenomenon known as inter-site interlink interference (ISI). To manage ISI, base stations need to perform interference testing or channel measurements. However, uplink transmissions from base stations can affect ISI or channel measurements, impacting their accuracy. Summary of the Invention

[0053] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. In the description of this application, unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship. For example, A / B can represent A or B. "And / or" in this application is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone, where A and B can be singular or plural. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple. In addition, to facilitate a clear description of the technical solutions of the embodiments of this application, the following points will be explained before introducing the solutions of this application.
[0054] (1) In this application, “instruction” may include direct instruction, indirect instruction, explicit instruction, and implicit instruction. When a certain instruction information is used to instruct A, it can be understood that the instruction information carries A, directly instructs A, or indirectly instructs A.
[0055] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a relationship between the other information and the information to be instructed. It can also indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent. Furthermore, the information to be instructed can be sent as a whole or divided into multiple sub-information pieces, and the sending period and / or timing of these sub-information pieces can be the same or different.
[0056] (2) In this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include direct transmission via the air interface or indirect transmission by other units or modules via the air interface. "Receive information from YY" can be understood as the source of the information being YY, which may include direct reception from YY via the air interface or indirect reception from YY by other units or modules via the air interface. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface. In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via a bus, wiring, or interface. Furthermore, unless otherwise specified, "transmission" includes receiving and / or sending. For example, transmitting signals can include receiving signals and / or sending signals.
[0057] (3) In this application, information C is used to determine information D, including both when information D is determined solely based on information C and when it is determined based on information C and other information. Furthermore, information C can also be used to determine information D indirectly, for example, when information D is determined based on information E, and information E is determined based on information C.
[0058] (4) The terms “comprising” and “having” and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product or device.
[0059] (5) In the various embodiments of this application, unless otherwise specified or logically conflicting, the terms and / or descriptions of different embodiments are consistent and can be referenced by each other. The technical features of different embodiments can be combined to form new embodiments according to their inherent logical relationship.
[0060] (6) In this application, "first" and "second" are used for descriptive convenience only to distinguish objects and are not intended to limit the scope of the embodiments of this application. They are not used to describe the order or sequence of features. It should be understood that the objects described in this way can be interchanged where appropriate so as to describe solutions other than those in the embodiments of this application.
[0061] (7) In this application, the words “exemplary” or “for example” are used to indicate that something is an example, illustration, or illustration. Any embodiment or design that is described as “exemplary” or “for example” in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words “exemplary” or “for example” is intended to present the relevant concepts in a specific manner.
[0062] Figure 1 The schematic diagram of the mobile communication system shown is a schematic diagram of the communication system 1000 used in the embodiments of this application. Figure 1 As shown, the communication system includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The wireless access network 100 may include at least one wireless access network device (such as...). Figure 1 110a and 110b in the above), may also include at least one terminal device (such as Figure 1 (Referring to 120a-120j in the original text). Terminal devices connect to wireless access network (WLAN) devices wirelessly, for example, via an air interface. WLAN devices connect to the core network wirelessly or via a wired connection. Core network devices and WLAN devices can be independent physical devices, or they can integrate the functions of core network devices and the logical functions of WLAN devices onto a single physical device. Alternatively, a single physical device can integrate some core network device functions and some WLAN device functions. Terminal devices and WLAN devices can be interconnected via wired or wireless connections. Figure 1 This is just a schematic diagram. The communication system may also include other network devices, such as wireless repeaters and wireless backhaul devices. Figure 1 It is not shown in the middle.
[0063] Radio access network (RAN) equipment is the access device that enables terminal devices to access a communication system wirelessly. RAN equipment can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a gNB in a 5G mobile communication system, a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes performing some of the functions of a base station. For example, RAN nodes can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). The RU can be included in radio frequency equipment or radio frequency units, such as in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).
[0064] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open RAN (ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented by a software module, a hardware module, or a combination of software and hardware modules. The embodiments of this application can be implemented by DU or RU. The CU here performs the functions of the radio resource control protocol and packet data convergence protocol (PDCP) of the base station, and can also perform the functions of the service data adaptation protocol (SDAP); the DU performs the functions of the radio link control layer and media access control layer of the base station, and can also perform some or all of the physical layer functions. For a detailed description of each of the above protocol layers, please refer to the relevant technical specifications of the 3rd generation partnership project (3GPP).
[0065] Wireless access network equipment can be macro base stations (such as...) Figure 1 110a in the text), can also be a micro base station or an indoor station (such as... Figure 1 110b) in this context can also be a relay node or a donor node, etc. The embodiments of this application do not limit the specific technology or device form used in the wireless access network equipment. For ease of description, network equipment is used as a shorthand for wireless access network equipment, and base station is used as an example of wireless access network equipment.
[0066] The terminal device also has wireless transceiver capabilities, enabling it to send signals to or receive signals from a base station. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station, mobile terminal device, etc. Terminal devices can be widely used in various scenarios, such as environmental IoT, device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, intelligent transportation, smart cities, etc. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technologies or device forms used in the terminal devices.
[0067] Base stations and terminal equipment can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminal equipment.
[0068] The roles of base stations and terminal devices can be relative, for example, Figure 1 The helicopter or drone 120i can be configured as a mobile base station. For terminal devices 120j that access the wireless access network 100 via 120i, terminal device 120i is a base station; however, for base station 110a, 120i is a terminal device, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base stations and terminal devices can be collectively referred to as communication devices. Figure 1 The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 1 The 120a-120j in the text can be referred to as communication devices with terminal equipment functions.
[0069] Communication between base stations and terminal devices, between base stations, and between terminal devices can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.
[0070] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal device can be executed by modules (such as chips or modems) within the terminal device, or by a device that includes terminal device functions.
[0071] For example, the network device provided in the embodiments of this application may be, for example, a Figure 1 In the case of 110a or 110b, the terminal device provided in this application embodiment can be, for example, 110a or 110b. Figure 1 Any one of 120a-120j.
[0072] The functions of the network devices or terminal devices involved in this application can be implemented by one device, or by multiple devices, or by one or more functional modules within one device, or by one or more chips, or by a system on a chip (SOC) or chip system. A chip system can be composed of chips or include chips and other discrete devices. The embodiments of this application do not specifically limit this.
[0073] It is understood that the above functions can be network elements in hardware devices, software functions running on dedicated hardware, a combination of hardware and software, or virtualization functions instantiated on a platform (e.g., a cloud platform).
[0074] For example, the relevant functions of the network device or terminal device in the embodiments of this application can be achieved through... Figure 2 This is achieved through the communication device 110.
[0075] Figure 2A schematic diagram of a possible communication device 110 is shown. It is understood that the communication device 110 includes means of the necessary form, such as modules, units, elements, circuits, or interfaces, to be appropriately configured together to perform this solution. The communication device 110 can be a network device or a terminal device, or a component (e.g., a chip) within these devices, to implement the methods described in the following method embodiments. The communication device 110 includes one or more processors 111. The processor 111 can be a general-purpose processor or a dedicated processor, for example, a baseband processor or a central processing unit. The baseband processor can be used to process communication protocols and communication data, while the central processing unit can be used to control the communication device (e.g., a network device, a terminal device, or a chip), execute software programs, and process data from the software programs.
[0076] Optionally, in one design, the processor 111 may include a program 113 (sometimes also referred to as code or instructions), which can be executed on the processor 111 to cause the communication device 110 to perform the methods described in the embodiments below. In yet another possible design, the communication device 110 includes circuitry (…). Figure 2 (Not shown).
[0077] Optionally, the communication device 110 may include one or more memories 112 storing a program 114 (sometimes referred to as code or instructions), which can be run on the processor 111 to cause the communication device 110 to perform the methods described in the following method embodiments.
[0078] Optionally, the processor 111 and / or memory 112 may include artificial intelligence (AI) modules 117 and 118, which are used to implement AI-related functions. The AI modules can be implemented through software, hardware, or a combination of both. For example, the AI module may include a RAN intelligence controller (RIC) module. For example, the AI module may be a near real-time RIC or a non-real-time RIC.
[0079] Optionally, the processor 111 and / or memory 112 may also store data. The processor and memory may be configured separately or integrated together.
[0080] Optionally, the communication device 110 may further include a transceiver 115 and / or an antenna 116. The processor 111, sometimes referred to as a processing unit, controls the communication device (e.g., a network device or a terminal device). The transceiver 115, sometimes referred to as a transceiver unit, transceiver, transceiver circuit, or transceiver, is used to realize the transmission and reception functions of the communication device through the antenna 116.
[0081] also, Figure 2 The structural composition shown does not constitute a limitation on the communication device, except... Figure 2 In addition to the components shown, the communication device may include more or fewer components than illustrated, or combine certain components, or have different component arrangements.
[0082] To support AI technology in wireless networks, AI nodes may also be introduced into the network.
[0083] Optionally, the AI node can be deployed in one or more of the following locations within the communication system: wireless access network equipment, terminal equipment, or core network equipment, etc. Alternatively, the AI node can be deployed independently, for example, in a location other than any of the aforementioned devices, such as in the host or cloud server of an over-the-top (OTT) system. The AI node can communicate with other devices in the communication system, which can be, for example, one or more of the following: network equipment, terminal equipment, or core network elements, etc.
[0084] It is understood that this application does not limit the number of AI nodes. For example, when there are multiple AI nodes, these nodes can be divided based on function, such as different AI nodes being responsible for different functions.
[0085] It can also be understood that AI nodes can be independent devices, or they can be integrated into the same device to achieve different functions. Alternatively, they can be network elements in hardware devices, software functions running on dedicated hardware, or virtualization functions instantiated on a platform (e.g., a cloud platform). This application does not limit the specific form of the aforementioned AI nodes.
[0086] AI nodes can be AI network elements or AI modules.
[0087] Figure 3 This is a schematic diagram of a possible application framework in a communication system. For example... Figure 3As shown, network elements in a communication system are connected via interfaces (e.g., NG, Xn, F1) or air interfaces. These network element nodes, such as core network equipment, access network nodes (RAN nodes), terminals, or one or more devices in operation administration and maintenance (OAM), are equipped with one or more AI modules (for clarity, ...). Figure 3 (Only one is shown in the image). The access network node can be a single RAN node or can include multiple RAN nodes, such as CU and DU. The CU and / or DU can also be configured with one or more AI modules. Optionally, the CU can also be split into CU-CP and CU-UP. One or more AI models are configured in CU-CP and / or CU-UP.
[0088] The AI module is used to implement corresponding AI functions. AI modules deployed in different network elements can be the same or different. Depending on the parameter configuration, the AI module can implement different functions. The AI module model can be configured based on one or more of the following parameters: structural parameters (e.g., at least one of the following: number of neural network layers, neural network width, inter-layer connections, neuron weights, neuron activation function, or bias in the activation function), input parameters (e.g., type and / or dimension of input parameters), or output parameters (e.g., type and / or dimension of output parameters). The bias in the activation function can also be referred to as the neural network bias.
[0089] An AI module can have one or more models. A model can infer an output, which includes one or more parameters. The learning, training, or inference processes of different models can be deployed on different nodes or devices, or they can be deployed on the same node or device.
[0090] Figure 4 This is a schematic diagram illustrating another possible application framework in a communication system. For example... Figure 4 As shown, the communication system includes a RAN intelligent controller (RIC). For example, the RIC can be... Figure 4The AI modules 117 and 118 shown are used to implement AI-related functions. The RIC includes near-real-time RIC (near-RT RIC) and non-real-time RIC (non-RT RIC). Non-real-time RIC primarily processes non-real-time information, such as data that is not sensitive to latency, with latency in the order of seconds. Real-time RIC primarily processes near-real-time information, such as data that is relatively sensitive to latency, with latency in the order of tens of milliseconds.
[0091] The near real-time RIC is used for model training and inference. For example, it can be used to train an AI model and then use that AI model for inference. The near real-time RIC can obtain network-side and / or terminal-side information from RAN nodes (e.g., CU, CU-CP, CU-UP, DU, and / or RU) and / or terminals. This information can be used as training data or inference data. Optionally, the near real-time RIC can deliver inference results to RAN nodes and / or terminals. Optionally, inference results can be exchanged between CU and DU, and / or between DU and RU. For example, the near real-time RIC delivers the inference result to the DU, and the DU sends it to the RU.
[0092] The non-real-time RIC is also used for model training and inference. For example, it can be used to train an AI model and then use that model for inference. The non-real-time RIC can obtain network-side and / or terminal-side information from RAN nodes (e.g., CU, CU-CP, CU-UP, DU, and / or RU) and / or terminals. This information can be used as training data or inference data, and the inference results can be delivered to the RAN nodes and / or terminals. Optionally, inference results can be exchanged between CU and DU, and / or between DU and RU. For example, the non-real-time RIC delivers the inference results to the DU, which then forwards them to the RU.
[0093] The near real-time RIC and non-real-time RIC can also be set up as separate network elements. Optionally, the near real-time RIC and non-real-time RIC can also be part of other devices. For example, the near real-time RIC can be set in the RAN node (e.g., in CU, DU), while the non-real-time RIC can be set in the OAM, cloud server, core network device, or other network device.
[0094] The embodiments of this application can be applied to 5G new radio (NR) wireless communication systems, achieving high data rates and low latency through the use of large bandwidth. In time-division duplex systems, such as... Figure 5As shown, DL typically occupies the majority of time resources, resulting in coverage imbalance between DL and UL. Compared to frequency division duplex (FDD) systems, TDD systems have poorer uplink coverage and greater latency.
[0095] To address the issues of uplink coverage and uplink latency in TDD systems, the SBFD scheme was proposed in release R 18 of the standard. In the SBFD scheme, a component carrier (CC) can include multiple sub-bands, and the transmission directions of different sub-bands can be different.
[0096] For example, Figure 6 This diagram illustrates time-frequency resource allocation in an SBFD scheme. In the three middle time units, a carrier can be divided into three sub-bands. The middle sub-band, designated UL, is the uplink sub-band available for uplink transmission. The top and bottom sub-bands are the downlink sub-bands available for downlink transmission, designated DL. This invention does not limit the existence of a guard band (GB) between the downlink and uplink sub-bands, or whether transmission is possible on the guard band if it exists.
[0097] In this designation, the upper sub-band refers to the higher-frequency sub-band, the lower-frequency sub-band refers to the lower-frequency sub-band, and the middle sub-band refers to the sub-band with a frequency between the upper and lower sub-bands. The first or last time unit can be called a non-SBFD time unit, and any time unit in the middle can be called an SBFD time unit. Time units can be, for example, time slots or symbols.
[0098] For example, Figure 7 This diagram illustrates time-frequency resource allocation in an SBFD scheme. In the three middle time units, a carrier can be divided into two sub-bands. The upper sub-band, designated DL, is the downlink sub-band available for downlink transmission. The lower sub-band, designated UL, is the uplink sub-band available for uplink transmission.
[0099] In the SBFD scheme, network devices can simultaneously transmit and receive signals using different frequency domain resources or subbands within the SBFD time unit. Currently, in the R19 standard, network devices can use a subband full-duplex scheme, while terminal devices can use a subband half-duplex scheme. When a terminal device uses a subband half-duplex scheme, it means that the terminal device can only receive or transmit signals within the SBFD time unit, and cannot receive and transmit signals simultaneously.
[0100] For the time-domain configuration of SBFD, there are two possible configuration methods depending on whether a time slot contains both SBFD and non-SBFD symbols. In one possible configuration method, the time-domain configuration of SBFD is at the time slot level, meaning that all symbols contained in a time slot are either configured as SBFD symbols or all are configured as non-SBFD symbols. In the other possible configuration method, the time-domain configuration of SBFD is at the symbol level, meaning that some symbols contained in a time slot can be configured as SBFD symbols, and others can be configured as non-SBFD symbols. This application does not limit the time-domain configuration method of SBFD. SBFD symbols can be symbols configured with SBFD operations, and non-SBFD symbols can be symbols without SBFD operations. For uplink transmission, non-SBFD symbols can be uplink symbols or flexible symbols; for downlink transmission, non-SBFD symbols can be downlink symbols or flexible symbols.
[0101] Compared to TDD systems, SBFD schemes offer increased uplink transmission resources available to terminal devices. Therefore, SBFD can effectively improve uplink coverage and reduce uplink latency.
[0102] In the SBFD scheme, signal power within one subband leaks into adjacent subbands, leading to interference between UL and DL, known as cross-link interference (CLI). Based on the source of the interference, CLI can be categorized into two types:
[0103] 1) Type 1, CLI between user equipment (UE) and UE (UE-to-UE CLI).
[0104] UE-to-UE CLI refers to the interference caused by an uplink signal transmitted by one UE in the same cell to a downlink signal received by another UE in the same or a neighboring cell. For example, in Figure 8 In this context, the interference caused by the uplink signal sent by UE#1 or UE#2 to gNB#1 to the downlink signal received by UE#0 from gNB#0 can be referred to as UE-to-UE CLI. This application's embodiments mainly focus on measuring and reporting UE-to-UE CLI.
[0105] 2) Type 2, CLI between next generation nodeB (gNB) and gNB (gNB-to-gNB CLI).
[0106] gNB-to-gNB CLI refers to the interference caused by downlink signals transmitted by one base station to uplink signals received by another base station. For example, in Figure 8 In this context, the interference caused by the downlink signal sent by gNB#0 to UE#0 to the uplink signal received by gNB#1 from UE#1 or UE#2 can be referred to as gNB-to-gNB CLI.
[0107] Figure 10 This illustration shows a scenario diagram of a flexible TDD provided by an embodiment of this application.
[0108] Dynamic / flexible TDD supports different uplink / downlink time slot ratios for different cells and supports dynamic changes in the uplink / downlink time slot ratio. For example, ... Figure 9 As shown, cell 1 uses an uplink / downlink time slot ratio of DDDSU, while cell 2 uses an uplink / downlink time slot ratio of DSUUU. If base station 1 and base station 2 are synchronized, then in time slot 3, the downlink signal sent by base station 1 will interfere with the uplink signal received by base station 2. This interference can be considered as CLI between base stations.
[0109] The following will combine Figures 1 to 9 The design and configuration methods of uplink silent resources and the power transmission methods of uplink non-silent resources provided in the embodiments of this application are described in detail.
[0110] Figure 10 A schematic diagram of a first resource provided in an embodiment of this application is shown.
[0111] In the NR system, with Figure 10 For example, when the subcarrier spacing is 15kHz, in the time domain, the length of each slot is 1 millisecond (ms), occupying 14 orthogonal frequency division multiplexing (OFDM) symbols, such as... Figure 10 In the mid-time domain, each time slot occupies 0-13, for a total of 14 OFDM symbols. In the frequency domain, each time slot occupies 12 consecutive subcarriers, such as... Figure 10 On the mid-frequency axis, there are 12 subcarriers, numbered 0-11. A resource block (RB) occupies one slot in time and 12 consecutive subcarriers in frequency, such as... Figure 10 In this context, RB#X and RB#Y are used. A Resource Element (RE) is the smallest unit of a resource, which occupies one OFDM symbol in time and one subcarrier in frequency.
[0112] Due to the existence of inter-base station CLI (CLI), it is necessary to measure and compensate for inter-base station CLI to suppress its impact on uplink transmission. UE uplink transmission can affect the accuracy of inter-base station CLI or channel measurements. Therefore, UE uplink transmission needs to remain muted on measurement resources used for inter-base station CLI or channel measurements. These resources are called first resources, or uplink muted resources; the two are equivalent. In other words, the UE does not perform first uplink transmissions on first resources. A first resource consists of one or more first resource elements (REs), which are REs not used for first uplink transmissions, also known as mutating REs.
[0113] The first uplink transmission here can be the physical uplink share channel (PUSCH), and optionally, it can also include the physical uplink control channel (PUCCH).
[0114] The first resource in the frequency domain can be a pattern type predefined by the protocol, or a pattern type configured by the base station through signaling. One specific implementation is that the first resource is a comb-2 mapping on the subcarriers, meaning that one subcarrier occupies every two subcarriers, or one subcarrier occupies every interval between subcarriers. Alternatively, the first resource can be considered to be located on consecutive odd-numbered subcarriers or consecutive even-numbered subcarriers in the frequency domain. Figure 10 As shown, on RB#X, the first resource includes consecutive odd-numbered subcarriers with index numbers 1, 3, 5, 7, 9, and 11 in the frequency domain.
[0115] In the time domain, the first resource can be a pattern type predefined by the protocol or a pattern type configured by the base station through signaling. One specific implementation is that the first resource occupies a maximum of two symbols within a time slot. For example, one symbol is located within the first three symbols of the time slot, and the other symbol is located within the remaining symbols, i.e., the fourth and subsequent time-domain symbols. This ensures that the first resource is located within the corresponding time-frequency resource ranges of the PDCCH and PDSCH, enabling the base station to measure the interference caused by the PDCCH and PDSCH separately, improving the accuracy of interference measurement and enhancing system performance. For example, for PUSCH mapping type A, the time-domain symbol of the first resource can be located in the first symbol of the time slot, or in the first valid symbol after the demodulation reference signal (DMRS) symbol, i.e., the symbol that can be used for the first uplink transmission. The time-domain symbol of the first resource can be located in the first symbol of the time slot and the first valid symbol after the DMRS symbol. For example, for PUSCH mapping type B, the time-domain symbol of the first resource can be located in the second, third, or fourth symbol within the time slot. Alternatively, the time-domain symbol of the first resource can be located in the second and fourth symbols within the time slot, or it can be located in the third and fourth symbols within the time slot.
[0116] Specifically, within a time slot, the first three symbols have different meanings and are located at different positions within the time slot for different reference starting points. For example, using the first symbol of the time slot as the reference starting point for the time domain symbols, the base station configures the first resource to be located on the second symbol. Regardless of which symbol within the time slot the PUSCH transmission begins from, the uplink silence resource is located on the second symbol of that time slot. As another example, using the start symbol of the PUSCH as the reference starting point for the time domain symbols, the base station configures the first resource to be located on the second symbol. If the PUSCH transmission begins from the third symbol within the time slot, then the first resource is located on the second symbol relative to the start symbol (the third symbol) of the PUSCH transmission; that is, the first resource is located on the fourth symbol of the time slot.
[0117] Optionally, for PUSCH mapping type A, the reference starting point of the time domain symbol can be the first symbol of the time slot, and for PUSCH mapping type B, the reference starting point of the time domain symbol can be the starting symbol of the PUSCH.
[0118] For the time-domain configuration of SBFD, there are two possible configuration methods depending on whether a time slot contains both SBFD and non-SBFD symbols. In one possible configuration method, the time-domain configuration of SBFD is at the time slot level; that is, all symbols contained in a time slot are either configured as SBFD symbols or all as non-SBFD symbols. In the other possible configuration method, the time-domain configuration of SBFD is at the symbol level; that is, some symbols contained in a time slot can be configured as SBFD symbols, and others can be configured as non-SBFD symbols. The first resource element in the first resource is only effective on SBFD symbols.
[0119] For example, if a time slot contains only non-SBFD symbols, even if the base station configures the first resource in that time slot, the first source will not be effective in that time slot; that is, the first resource element will not be effective. As another example, if a time slot contains some SBFD symbols and others non-SBFD symbols, and the base station configures the first resource in that time slot, the first resource element configured on the non-SBFD symbols will not be effective, while the first resource element configured on the SBFD symbols will be effective. Furthermore, for PUSCH transmissions spanning multiple time slots, such as repeated PUSCH transmissions across multiple time slots, PUSCH transmissions mapping transport blocks (TBs) across multiple time slots, or multiple PDSCH transmissions scheduled by a DCI across multiple time slots, similarly, only the first resource element configured on the SBFD time slot or SBFD symbol will be effective.
[0120] Optionally, the first resource cannot be configured on symbols containing PUSCH DMRS, phase-tracking reference signal (PT-RS), or sounding reference signal (SRS). Alternatively, if the first resource is configured on a symbol containing PUSCH DMRS, PUCCH DMRS, PT-RS, or SRS, then the first resource on those symbols is invalid.
[0121] Optionally, the first resource can be located in one or more time slots. When the first resource is located in multiple time slots, the patterns in each time slot can be the same or different.
[0122] Figure 11 The flowchart shown is a method for configuring uplink silent resources according to an embodiment of this application, including the following steps:
[0123] Step S1101: The network device sends a first signaling message to the terminal device. Correspondingly, the terminal device receives the first signaling message from the network device.
[0124] Optionally, the first signaling may be radio resource control (RRC) signaling or a system information block (SIB).
[0125] The base station configures N sets of first resources for the UE via first signaling, where N is a positive integer greater than or equal to 1. The first resources are not used for the first uplink transmission; therefore, they can also be called uplink silent resources. The first uplink transmission can be a PUSCH. Optionally, the first uplink transmission can also be a PUCCH.
[0126] The primary resource can be of the BWP-specific type, the UE-specific type, or the cell-specific type. For example, out of N sets, only one set is of the BWP-specific type, and the remaining N-1 sets are of the UE-specific type.
[0127] For example, if the first resource is a BWP-specific type or a BWP group-specific type, then each BWP or BWP group is configured with its own dedicated first resource. Optionally, the first resource can be configured on some BWPs or BWP groups, while not configured on others. The first resource is only valid for the associated BWPs or BWP groups and is invalid for other unassociated BWPs or BWP groups.
[0128] For example, if the first resource is a UE-specific type, it is valid for all BWPs for that UE.
[0129] For example, if the first resource is a cell-specific type or a cell-common type, then the first resource is valid for all UEs and all BWPs in that cell.
[0130] Step S1102: The network device sends a second signaling message to the terminal device. Accordingly, the terminal device receives the second signaling message from the network device.
[0131] S1102 is an optional step. The base station can dynamically activate / deactivate the first resource as needed. For example, if the current inter-site CLI is relatively small, or if the inter-site CLI has little impact on uplink transmission, the base station can deactivate the first resource. This avoids the impact of the resource overhead of the uplink silent resource on uplink transmission and improves the flexibility of base station scheduling. In this patent application, activation and effectiveness have the same meaning, and inactivation and ineffectiveness have the same meaning and can be arbitrarily substituted.
[0132] Optionally, when the base station indicates effectiveness or activation via the second signaling, it can instruct N1 sets of first resources out of N sets to be effective or activated. N1 is less than or equal to N and is a positive integer. Optionally, the base station can divide the N sets of first resources into N2 sets of first resources groups, where N2 is less than or equal to N and is a positive integer. Each first resource group contains one or more sets of first resources, and the base station can instruct one of the first resource groups to be effective or activated.
[0133] Optionally, the base station can instruct, via a second signaling, that all first resources in the N sets of first resources are inactive or disabled. The base station can also disable or deactivate only a portion of the first resources or groups of first resources; see the section above for instructions on enabling or activating them.
[0134] The second signaling can be downlink control information (DCI) or MAC control element (MAC CE).
[0135] DCI can be a scheduling DCI, such as a scheduling PUSCH DCI, for example, DCI format 0_0, DCI format 0_1, DCI format 0_2, DCI format 0_3, etc. Specifically, new indicator fields can be introduced into these DCI formats to indicate the above functions, or some existing indicator fields can be reused to indicate the above functions, such as the sounding reference signal request (SRS request) field, the time domain resource assignment (TDRA) field, and the modulation and coding scheme (MCS) field.
[0136] 1. Reuse SRS request fields
[0137] The existing SRS request field is used to trigger aperiodic SRS, and this indication field includes 2 bits or 3 bits.
[0138] In one embodiment of the present invention, some or all of the bits in the indication field can be reused to indicate whether the first resource is activated or effective. For example, when the indication field includes 2 bits, the first bit is used to indicate whether the first resource is activated or effective, and the second bit is used to trigger aperiodic SRS; or, both bits in the indication field are used to indicate whether the first resource is activated or effective. As another example, when the indication field includes 3 bits, the first bit is a non-supplementary uplink (SUL) / SUL indication, with specific indication methods referring to existing technologies; the second and / or third bits are used to indicate whether the first resource is activated or effective. As yet another example, when the indication field includes 3 bits, the first bit indicates whether the indication field is used for first resource indication or aperiodic SRS indication. For example, if the first bit is '0', then the second and third bits are used to indicate aperiodic SRS indication, with specific indication methods referring to existing technologies and not repeated here; if the first bit is '1', then the second and / or third bits are used to indicate whether the first resource is activated or effective.
[0139] In another implementation, one or more indication states of the indication field can be reused to indicate whether the first resource is activated or effective. For example, when the SRS request field takes the value '10' and / or '11', it indicates that the first resource is not activated / ineffective, or indicates that the first resource is activated / effective. The indication states corresponding to other values can refer to the prior art.
[0140] 2. Reuse TDRA domain
[0141] The existing TDRA field is used to indicate PUSCH time-domain resource allocation. Specifically, the base station configures a PUSCH time-domain resource allocation list through higher-layer signaling such as RRC signaling. This PUSCH time-domain resource allocation list contains L PUSCH time-domain resource allocation indicators, where L is a positive integer. Each PUSCH time-domain resource allocation indicator includes at least parameters such as mapping type, start symbol, and length, as detailed in existing technologies. This indicator field includes... Each bit has a corresponding L values that correspond one-to-one with the L PUSCH time-domain resource allocation indicators. In this way, the corresponding PUSCH time-domain resource allocation information can be indicated through the TDRA field.
[0142] In the present invention, indication information on whether the first resource is activated or effective can be introduced into each of the L PUSCH time-domain resource allocation indications configured in the above-mentioned RRC signaling and other higher-level signaling configurations. In this way, the activation / effectiveness of the first resource can be indicated through the TDRA field.
[0143] 3. Reuse MCS domain
[0144] The existing MCS field is used to indicate the MCS of PUSCH, and this indication field consists of 5 bits.
[0145] In one embodiment of the present invention, some or all of the bits in the indication field can be reused to indicate whether the first resource is activated or effective. For example, the first X bits of the indication field are used to indicate whether the first resource is activated or effective, while the remaining bits are still used to indicate the MCS, where X is a positive integer.
[0146] In another implementation, the MCS value of the indicator field can be reused to indicate whether the first resource is activated or effective. For example, when the MCS value indicated by the indicator field is greater than a first threshold, the first resource is not activated / effective; or, when the MCS value indicated by the indicator field is less than the first threshold, the first resource is activated / effective. Extendedly, the value of the first threshold can refer to the MCS threshold used in the prior art to determine the temporal density of the phase tracking reference signal (PT-RS), such as ptrs-MCS3.
[0147] Alternatively, MACE CE can be used to replace DCI to implement functions such as first resource indication and activation.
[0148] Step S1103: The terminal device sends a first uplink transmission to the network device. Correspondingly, the network device receives the first uplink transmission from the terminal device.
[0149] Optionally, the network device performs measurements on the first resource, including inter-site cross-link interference or channel measurements.
[0150] In one specific implementation, the UE performs resource mapping before performing the first uplink transmission. If the scheduled or allocated time-frequency resources include first resource units, the data of the first uplink transmission is not mapped to these first resource units. Optionally, according to the activation / effectiveness indication information in the second signaling, the data of the first uplink transmission is not mapped to these activated / effective first resource units; however, the data of the first uplink transmission may be mapped to inactive / ineffective first resource units.
[0151] The first value is the ratio of the energy per resource element (EPRE) of the first uplink transmission to the EPER of the DMRS of the first uplink transmission.
[0152] In one specific implementation, when the UE performs a first uplink transmission, the uplink transmit power remains consistent across the symbols allocated in the first transmission. If some symbols in the first uplink transmission are configured with first resource elements, while others are not, a first value on the time-domain symbols configured with first resource elements is greater than a first value on the time-domain symbols not configured with first resource elements. Here, the first value is the ratio of the energy per resource element (EPRE) of the first uplink transmission to the EPER of the DMRS of the first uplink transmission. This configuration can be predefined by the protocol or configured by the base station via signaling.
[0153] For symbols configured with first resource elements, since there are fewer available REs on these symbols compared to those without first resource elements, the transmit power of the first transmission on the REs of these symbols needs to be increased. When the frequency domain resource of the first resource is comb-2, and the first value is taken in the dB domain, the first value on the time domain symbol including the first resource element is equal to the first value on the time domain symbol excluding the first resource element plus 3 dB. When the first value is taken in the linear domain, the first value on the time domain symbol including the first resource element is equal to twice the first value on the time domain symbol excluding the first resource element.
[0154] For example, when the first uplink transmission is PUSCH, the ratio of PUSCH EPRE to DMRS EPRE on the time-domain symbol without a configured first resource element can be determined according to Table 6.2.2-1 in 3GPP protocol TS 38.214v18.0.0. For example, when the ratio of PUSCH EPRE to DMRS EPRE on the time-domain symbol without a configured first resource element is 0dB, the ratio of PUSCH EPRE to DMRS EPRE on the time-domain symbol with a configured first resource element is 3dB.
